    Zener Diode

    In looking out on the wonderfull warehouse called Ebay, I noticed that these diodes are avaliable in: 4.7V @ .5 watt, and 4.7V @ 1 watt.

    Which should I use for fooling the PCM, or does it not really matter?

    Mopar Performance computers need the 4.7V, 1 watt diode. Stock computers need the 4.3V, 1 watt diode.

    yeah if you only use the 0.5watt diode it might burn up. Thats what I used at first and it didn't last very long at all before it stopped working. Also I would suggest getting one of the adjustable ones so you can dial in whatever voltage you need. I was able to make one up for only $5 in parts from radio shack. Check out this site on how to make it.

    Cool, thanks for the link. I actually got a 4.3V and a 4.7V both are 1 watt, so I should be all set. Jdawg, if you already put one in the mail thanks. If you haven't yet, don't bother, as I've got a couple on the way.
